Toallrwhom itmay ma Be itknown that I,

FLTNGER, a. citizen of the United States, re-

siding at Hobart, in the county of King and State of Washington, have invented certain new-and useful Improvements in Concrete Shingles. a

.,My invention relates to improvements in shingles, and it consists in the combinations,

constructions and arrangements herein described and claimed. y n

An object of the invention is the provision of a novel shingle which has means whereby it can be secured firmly in place 5 in association with other like shingles to produce a fire proof and leak proof roof covering which willlie close to the sheeting boards on which the roof covering is ,dis-

' posed.

' A. furtherLobject of the "invention is the provision of a shingle of'the character described which is practically impervious to the weather and which need not have any openings therethrough such as ordinamly 5 are necessary for the passage of nails which are used to. secure vshingles provided prior' to the inventionin place.

Other objects-and advantages of the invention .will be ap arent from the following description, considered in conjunction with the accompanying. drawings, in which Figure l-is "a plan view of a fragmentary portion of a roof covering formed "of shingles embodying the invention.

I 'Figure 2 is a section along the line 2 -2 of Figure 1.

Figure 3 is a perspective view of one of the improved shin les.

Figure 4 is a raginentarylongitudinal sectional view of the upper end portion of.

one of the shingles, showing an attaching tab partially embedded in the uroer end portion of the shingles,

HnL- thanthat of the shingles shown in the preceding views,

tive view of still another'form of shingle embodying the invention. v

The improved shingle'comprises a body- 1 madeof concrete or other suitable incombustible'material. The body 1 increases uniformlv inthickness from its upper end to its a lower end andmay.have'an desirable configuration.

L A metallicattaching tab coinprisesa corru-gated portion 2 which is imbedded. in the body'of the shingle midway between the side 'edges of the shingle body atthe upperend of the latter whenthe' shingle is formed and an extending portion 3 which extends beyond the upper end of the shingle body and may be provided with an opening 4' for a .pur o'se to bepresently stated.

e side edges of the'shingle body preferably are straight and parallel. The upper edge .of the shingle preferably extends .at 7

right angles to the direction of length of the side edges of the shingle body. The lower edge of the shin 1e body mayhave any desirable configura ion and may curve concavely at 5 for equal distances from the op-.

posite ends thereof and then extend at 6 at right angles to the direction of length of the I side edges of the shingle body, thus producing a prolongation or extending portion 7 at the lower end of the'shi'ngle midway of the width of the latter, as best seen in Figures 1, 3 and 5, the lower edge of the shingle shingle and somewhat nearer to the lower end of the shingle body than to the upper end thereof. The right angular fastening.

memberalso includes atransversely corrugated arm or engaging portion 10 which extends from the body of the shingle substantially at ri'ht angles to the lower face of the latter, v

The shingle body also is formed with opposite notches-11 in the-side edges'thereof.

' These notches extend obliquely between the 'lowe'r-a nd'fuppei' faces of theshingle body 1 so that the upper, ends of the notches are slightly-nearer to the upper end of the.

' shingle bodythan the lower ends of said notches .The notches 11 are located in the-- side edges of the shingle body in the plane which is somewhat. nearer to thelower end ofthe shingle than to the-upper end of the shin 1e but farther' from thelowerend of. .thes in 1e than the fastening member 8.q10.

hingle bodyis reenforced by a wire" frame which is imbedded in the material of which the shingle body is form'ed midway betweenthe top and bottom faces oftthe shingle body.

verse members 13*and 13, respectively. which extend in the shingle body near: the ends thereof, a1 1d diagonal members lta'nd 15,

respectively, each of'which extends between opposite corners of the 'reenforcing wire frame. One of the diagonal reenforcing members, as 14 may be twisted around-the other diagonal reenforcing member at the center-of the reenforcing wire frame, as at From the foregoing descriptionof the various parts of the device, the operation thereof may be readily 'understdod.

A plurality of the improved shinglesmay.

be used to form a roof covering, a side covering for a frame structure, or for like use. When used to produce a roof covering, the shingles are laid in courses as shown in Figs. 1 and 2. The course of shingles 1- nearest an eave of the roof are laid in-position to overlap a course of eaves or starting shingles 17 which may differ from the shingles 1 only in that the former do have the prolongations 7, the slots 11, and the fastening member 810 of' the latter. The

fastening members 8.-1O of-the first course ofshingles'l therefore may be omittedand the portions of the eaves shingles 17 and of.

the shingles 1 of the firstcourse which are exposed to the weather are secured to the roof sheeting 18 by nails 19 which are driven through preformed openings in the shingles 1 of the first course and through the eaves shingles, cement mortar being used to seal the upper ends of the openings in the shingles in whichthe nails 19 are partially received and to cover the upper ends of the nails.

The attaching tab 3 at the upper end of each shingle is secured to the roof sheeting bynails 20 which are driven through the openings 4 into the roof sheeting. The

-, notches 1]. of adjacent shingles in the same course register with each other and are filled with concrete mortar, as at 21. The

This wire frame may com-i. prise longitudinal members 12 whichextend in the shingle body nearits side edges, trans-- 'the' transverse median line and the lower.

shingles of adjacent courses are staggered and the depending portion- 10 of each shingle 1 of the courses above the first course of shingles l is projected into the concrete mortar inthe notches 11 between the twb adjacentjshingles '1 of the next lower course beforeithe concrete mortar hardens and the shingles 1- .then is pressed down flatwise onto the overlapped .portionio'f the adjacent shingles ofthe next. lower course, whereby the shingles will be secured closelyand firmly to one another and to thereof sheeting and .a leak proof and fire proof roof 5 thickness toward-its lower end'assures a' relativel thickroof covering when a given Obviously, the invention is susceptible to embodiment in forms other than thatwhich- -ing members extending in said body and joined to said longitudinal and transverse wire members.
